3. Introduction
Wireless Electrical Transmission as the name shows is the Transmission of Electrical Energy without wires to any place on Earth. Even to the most remote areas.
The Electrical energy is first converted into Microwaves then beamed to a Geosynchronous satellite and Beamed back on Earth where needed and converted back to electrical energy. Where it can be used to power Electrical Equipments.

4. Background
Nikola Tesla ( ) The Father of Wireless Electricity.
                        
                             
Tesla's many inventions include high-frequency generators (1890) and the Tesla coil (1891), a transformer with important applications in the field of radio communications

5. Innovations Alternating Current.
In 1899 Nikola Tesla was able to light lamps over 25 miles away without using wires. Also the high frequency current of tesla coil, could light lamps filled with gas (like Neon).
In 1964 William. C Brown demonstrated a Rectenna which would convert Microwaves Power to Electricity.

6. Wireless Electricity Transmission And Reception Using Microwaves

7. Rectenna Design
5000 Mw Receiving Station (Rectenna). This station is about a Mile and Half long.
The Rectenna Would be Visually Transparent so that it would not interfere with Plant life.

8. Advantages of Using Microwaves for Wireless Electricity Transmission
High Efficiency Up to 85% .
Power Level is Well Below International safety standard.
Frequency is up to 2.45 GHz of the Micro Beam.
Retro-directive Beam Control capability.
No Air Or water Pollution is Created.
During Generation power can be Beamed to the location Where it is needed.
We don’t have to invest in a large Electrical Grid.
If Microwave Beams Carrying power could be beamed uniformly over the earth they could power cell phones, but the antenna length should be cm square.

9. System Losses Of Wired Electricity Transmission
Electricity Grid
10%
Distribution/
Transmission
32.7 GJ
Customer
36.3GJ
Power
Supply 40%
19.6 GJ
We lose, on average, 80% of the energy we extract when using it for electronic products

10. Advantages Of Wireless Electricity Transmission
Power Loss is very less as compared to Wired Electricity Transmission.
There is no need of Transmission Lines.
Health and Environmental Experiments claim that Wireless Electricity Transmission Using Microwaves and laser is safe.

11. Disadvantages of wireless Electricity Transmission
The Size of Rectenna will be Massive.
Would Require a Network of hundreds of satellites.
The Cost of this Prototype Project Will Be $74 Billion approx.
Interference with other Electronic Devices will be there.

12. Issues Conclusion Who will Fund?
NASA: Funding The research, in charge of space flight for the United States Of America.
NASA: Would be launching the satellites and doing Maintenance.
Conclusion
More Reliable Than Ground Based Solar Power Generation.
More Reliable Than Wired Electricity Transmission.
In Order To Have Wireless Electricity Transmission To Become a Reality, Following Things Have To Happen:
#Government Support.
#Cheaper Launch Prices.
#Involvement Of The Private Sector.
